With the TURBOVAC iR variants, vacuum producer Leybold is launching a new, complete turbomolecular pump collection, technologically derived from the confirmed TURBOVAC i family. “ diaphragm seal exchange the former TURBOVAC ClassicLine pumps and meet, for example, the necessities of our high-end analysis prospects – similar to the main analysis institutes CERN or DESY,” summarizes the responsible product supervisor, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for versatile remote operation from 3 meters to distances of 1 kilometre. In all aspects the merchandise had been additionally designed to withstand the challenges that are present in environments with excessive to very high ionizing radiation. “For this, we provide particular cable lengths of up to 200 meters, and also the option for the users to use their very own cables,” explains product manager Petr Lastovicka. According to Lastovicka, the iR fashions had been developed utilizing the present material knowledge of the research neighborhood: As a outcome, the materials they contain have radiation tolerances of up to 1 million grays (Gy).
In diaphragm seal with the ion getter and non-evaporable getter pumps, so called ultra-high vacuum pumps, “These attributes set them aside from standard market fashions, that are assembly the market requirements however not specifically those needed for the actual circumstances encountered in analysis centers,” says Petr Lastovicka. This is different with the TURBOVAC iR product sequence: on the one hand, they were developed for the special requirements regarding cable size and radiation tolerance. “In addition, we can provide the TURBOVAC iR pumps combined with our ion pumps and NEG pumps, which different suppliers cannot supply as a bundle,” adds Lastovicka. TURBOVAC iR matches completely well within the TURBOVAC i eco methods as other products similar to accessories or the software LeyAssist may be utilized as properly.
The backside line is that the new iR fashions are designed to fulfill the technical necessities of the high-energy physics market. This makes them predestined for purposes corresponding to synchrotrons (particle accelerators), cyclotrons (circular accelerators), linear accelerators and free-electron lasers. “In these areas, users can remove the electronics and place them in areas

the place they do not appear to be exposed to radiation,” explains Petr Lastovicka.
Another elementary situation in these software areas is absolutely the purity of the pump: this core requirement is fulfilled by the oil-free operation of the bearing system of the new TURBOVAC iR sequence. The TURBOVAC iR also supports all relevant communication options of the TURBOVAC I, USB, 15-pin digital I/O and all serial and fieldbus choices of the TURBO.DRIVE 500e. Another advantage: The built-in, new TURBO.DRIVE controller mechanically acknowledges the pump model and instantly adjusts to the particular operating modes.
The TURBOVAC iR range fully covers all current members of the TURBOVAC i family with pumping speeds from ninety to 950 l/s. In parallel, Leybold will successively broaden the accessories vary of supporting controllers and cable options to meet customer needs for

extra cable lengths and clever options. The intelligent Controller TURBO.DRIVE 500eC has been released in April and the TURBOVAC iR sizes 1350 and 1450 will observe in the third quarter of 2022 along with the more highly effective controller option to understand even longer cable lengths.
